Glycosyltransferase group 1 domain containing gene family

Reviewed April 2014

What are the glycosyltransferase group 1 domain containing genes?

Genes in this family provide instructions for making enzymes that act as glycosyltransferases. Glycosyltransferases modify molecules including proteins, sugars, and fats (lipids) by adding single or multiple sugar molecules to them through a process called glycosylation. Each sugar is transferred from one molecule, called the donor, to another molecule, called the acceptor; the donor and acceptor molecules are often proteins or lipids. Glycosylation modifies the acceptor molecules so they can perform a wider variety of functions. It often takes multiple glycosyltransferases to complete the process of glycosylation on a single protein or lipid.

Mutations in genes in the glycosyltransferase group 1 domain containing gene family disrupt the normal glycosylation of proteins and lipids and impair their function. Because glycosylation is performed on a variety of proteins and lipids that are involved in many functions throughout the body, changes in glycosyltransferase genes can cause a range of disorders that affect different body systems.

Which genes are included in the glycosyltransferase group 1 domain containing gene family?

The HUGO Gene Nomenclature Committee (HGNC) provides a list of genes in the glycosyltransferase group 1 domain containing family (http://www.genenames.org/genefamilies/GLT1).
